AR70DFF
AR detection lens Mer-AR70DFF is a straight-tube full-frame AR detection lens, specially designed for the optical performance detection and production process of AR equipment and modules. It is especially suitable for detection systems for AR optical machines or AR glasses with high PPD and large field of view angles. It provides high-precision and high-efficiency solutions for AR product research and development, production and quality control, and has the following core advantages:
● Full frame ultra-high definition AR detection
●150 high PPD
●The field of view angle is up to 70°
● Ultra-low stray, high transmittance
●High resolution
● Customizable automatic focus function
Features
AR detection lens Mer-AR70DFF has many core technical advantages:
Ultra HD PPD
In response to the growing pixels of AR optical machines, this lens has made special designs for the development of high-pixel AR optical machines. While meeting the research and development and testing of ultra-high-definition AR optical machines, it also meets the needs of mass production and testing of ultra-high-definition AR optical machines.
high resolution
This lens has a higher resolution, up to 0.4@100lpmm, which can simulate human eye imaging more clearly and obtain better image details and image quality.
Automatic focus function can be added
In order to meet customers' equipment integration needs, this lens can be purchased with an additional automatic focus module, saving time for customers' research and development and helping customers' products to quickly launch them to the market.
Small size, saving detection space
The size of this lens is better than industry indicators, and it finds the best balance between performance and size. While ensuring that the lens optical parameters meet the testing needs, it minimizes the lens size to the maximum extent, facilitates installation and installation, and makes inspection more flexible. The aperture can be replaced to meet the detection needs in different scenarios.
